You havent described what the actual problem is.... I assume the VPN tunnel is not connecting.

Is the modem or the snapgear doing the authentication with the ISP? Have you rebooted the snapgear after configuring?

I recall doing MANY VPN's with snapgear, and I never had a problem with them. Although for all PTPP tunnels we used the same model snapgear on each end.

What happens if you try to use an OS native vnp client? Windows built-in VPN client - does that work?

Ensure the tunnel password meets secuirty criteriea, and do you get any kind of error message? Also, increase the timeout value to 120 and check the snapgear logs. They will inidicate how far the VPN gets before it drops out, and will indicate the problem.

There doesnt seem to be any kind of problem with the snapgear tunnel, as you said that it works perfectly with windows VPN client. (unless you meant the opposite).

From what i gather in your posts, the problem seems to be with TheGreenBow VPN client, and since you may not have a password on the IPSec account this could be the problem. Many VPN clients require a password to connect, and a blank or null password will not work.

Let me know how you go with the few tweaks and changes, and confirm that the VPN does work with Windows VPN client, as this will demonstrate the snapgear is configured correctly.

may be I misunderstood from the first place,,,,,What I meant here, is that I "configured and Enable Routing and Remote Access" on the windows 2003 server which is sitting behind the SG300, then I enabled port forwarding (PPTP: 1723) on SG300 ,,,,,and I configured an XP client to connect to the VPN server (win2003),,,,,,in that configuration I have used native microsoft VPN.

when you would have asked me : ( What happens if you try to use an OS native vnp client? Windows built-in VPN client )) I thought you meant by using native VPN for microsoft ,,,,but you meant "Client" only.

VPN clients require a password to connect, and a blank or null password will not work.

1- Tunnel Settings
------------------
For the "Remote Address" textbox there are only three options (Static IP address , Dynamic IP address and DNS hostname address) we have to choose one of these three only, I chose : "Dynamic IP address" .

I tried to match every thing on "TheGreenBow = TGB" client to be same as the router (SA , key, ID,,,etc) but still VPN does not get established,therefore I could not find useful information from the logs

It seems the application is sending the connection, but is not getting a reply. Consider that the snapgear is not showing any log information about an incoming connection, I would have to say (without inspecting the logs myself) that the VPN connection is not being established at all.

The application is not successfully contacting the snapgear, or the snapgear is not successfully accepting/recognising the incoming connection.

I think someone with some experience of TheGreenBow app will have an idea on what you can look for.

Tunnel Settings Screenshot - have you defined the 'default gateway' elsewhere in the router? Try adjusting the 'keying' to an alternate setting.

Local & Remote Endpoint Setting Screenshot - Try using an IP address instead of the snapgear hostname. Ensure the hostname is correct if you really dont want to use the IP addy (although I recommend using IP addressing only as it is one less potential problem). internal and external IP respectively.

According to the logs, the VPN connection is not progressing any further than this.

Lastly, check the Snapgear capabilities as they may support PTPP VPN snapgear to snapgear only.

Hope this helps.
